DOUBIE-LINK GUARD.

Specification of Letters Patent.

Patented May 16, 1916.

Application filed .Tune 1, 1915. Serial No. 31,526.

To all whom #may concern.'

Be it lknown that I, Manco G. ZoNGARo, `a citizen of the United States,residing at Portland, in the county of Multnomah and State -of Oregon,have `invented certain new and useful Improvements in Double-LinkGuards; and I 'do declare the following vto be a full, clear, and exactdescription of the invention, such las will enable others skilled in theart `to which it appertains to make and luse the same.

This invention relates to improvements in open rings or links and moreparticularly to the closures therefor, and which are -known as doublellink guards.

The object of the invention is to provide a device of this characterwhich `is especially designed for use in logging campsfor attach--in'gcables employed for use onvfallen trees and which is so constructedthat the cable may -vbe iattached to both members thereof avoided.

With these and otherobjects in view, the invention consists of certainnovel features of construction, and ythe combination and arrangement ofparts as will be more fully described and claimed.

In the accompanying drawings: `-Figmre 1 `represents a side elevation-of a link guard constructed in accordance with this invention with theends of the lcable secured to the hooks of the link; Fig. 2 is alongitudinal section; Fig. 3 `is a transverse section taken on the 4line3 3 of Fig. 2; Fig. 4 isa similar view taken on the line H of Fig. 2. Inthe embodiment illustrated an oblong 'link 1 :is shown having an openingin one side `member thereof, thusv `forming `hook shaped ends 2 and 3,the bills 4 of which extend towardeach other andare arranged inrlongitudinal ialinenient, said bills being provided in their freeterminals with sockets 5 for a purpose to be described. A closure 10 forthese hooks 2 and 3 is shown pivotally mounted on the side bar of thelink at a point oppositethe space between the bills 4 of the hooks 2 and3 and which is designed to span the space between the bases and thebills of the hooks, the bases G of said hooks being joined by a reducedneck 7 having shoulders at its opposite ends which serve as stops forlimiting the longitudinal movement of the closure which is pivotallymounted on said neck. This closure 10 is shown in the form of a hollowcasing having a tubular bearing member 11 at one end thereof. of a sizedesigned to encircle `and freceive the neck 7 which joins the bases ofthe hooks 2 and 3 of the link. Projecting from this tubular member 11 isthe hollow casing 12, the side walls of which are spaced apart adistance substantially equal to the thickness of the bases of the hooksand tapers toward its free end which is `designed to fit between thebills 4 of the hooks 2 and 3, said casing being of a Width correspondingto the distance between the bills 4 of said hooks 2 and 3. Disposedwithin the casing 12 is a substantially U- shaped spring 13, the crossbar of which is 4provided with a plurality of laterally extending loops14, five being here shown, two extending in `one direction and three inthe opposite direction, the central loop being secured to the end wallof the free end of the casing by a rivet or other suitable means. ThisU-shaped spring is'of a size to fit within the casing 12 with the arms15 thereof arranged in close proximity to and parallel with the sideedges of said casing, said arms being provided at their free ends withoutwardly projecting laterally extending studs 16 which pass throughapertures 17 in the edge walls of the casing 12 adjacent the free outerend thereof and which are so `positioned 'that when the closure isoperatively disposed these studs will enter the sockets 5 in theterminals of the bills 4 and thereby reliably hold the closure inposition and form two complete members for the link, said closuredividing said link transversely.

Two push buttons or `headed `pins 18 are mounted to slide laterally inthe edge walls of the casing 12 with their inner ends positioned toengage the outer faces of the arms 15 ofthe springv 13 so that whenthese pins are compressed toward each other these arms 15 are similarlycompressed, thereby forcing the studs 1G carried thereby inward and thusreleasing them from the sockets 5 of the hook bills.

From the above description it will be obvious that should this link beemployed for connecting the ends of a cable C which are tied orotherwise engaged with the hooks 2 and 3, that on the closing of theclosure 10, said ends will be held entirely separated in spaced relationand will exert their pulling action on the curved portion of the hookswhich have a similar resistance to breakage, and it will thus notinterfere with the operation of the closure in any way. When it isdesired to disconnect these cable ends or any other articles with whichthe link has been attached, it may be readily accomplished by simplypressing together the pins or push buttons 18 at opposite edges of theclosure and thus simultaneously disengage the studs 16 from the sockets5 in the hook bills and thus Vpermit the closure to swing laterally intoopen position and the hooks 2 andB to be readily disengaged from thearticle or articles with which they were connected.

While this link is shown and described for use in connection with acable, it is obvious that it may be employed for many other differentpurposes, the gist of the invention residing in the peculiar means forclosing the link and forming a double guard therefor.

I claim as my invention:

1. The combination of a link having' hook-shaped ends with the bills ofsaid hooks arranged in alinement and spaced apart, a closure for saidhooks pivotally mounted on the link at a point opposite the spacebetween the bills thereof, said closure spanning the space between saidhook bills and the bases thereof and corresponding in width to thedistance between said bills, the terminals of said bills having socketstherein and said closure having spring pressed studs positioned to entersaid sockets when the closure is in operative position, and means forsimultaneously releasing said studs.

2. The combination of a link having hook-shaped ends with the bills ofsaid hooks arranged in alinement and spaced apart, a closure for saidhooks pivotally mounted on the link at a point opposite the spacebetween the bills thereof, said closure spanning the space between saidbills, the terminals of said bills having sockets therein, said closurebeing hollow and having a substantially U-shaped spring mounted thereinwith its arms posit ioned at the side edges of the closure, studscarried by the free ends of said arms and extending outwardly inopposite directions through the edges of said closure in position toenter the sockets of said bills, and means for compressing said arms torelease said studs.

3. The combination of a link having hook-shaped ends with the bills ofsaid hooks arranged in alinement and spaced apart, a closure for saidhooks pivotally mounted on the link at a point opposite the spacebetween'the bills thereof, said closure spanning the space between saidhook bills and the bases thereof and corresponding in width to thedistance between said bills, the terminals of said bills having socketstherein, said closure being hollow and having a substantially U-shapedspring mounted therein with its arms positioned at the side edges of theclosure, studs carried by the free ends of said arms and extendingoutwardly in opposite directions through the edges ofsaid closure inposition to enter the sockets of said bills, and pins slidable in theedge walls of said closure and positioned to engage said arms forcompressin them to release said studs.

4f. The combination of a link having hook-shaped ends with the bills ofsaid hooks arranged in alinement and spaced apart, a closure for saidhooks pivotally mounted on the link at a point yopposite thespacebetween the bills thereof, said closure spanning the space betweensaid hook bills and the bases thereof and corresponding in width to thedistance between said bills, the terminals of said bills having socketstherein said closures being hollow and having a substantially U-shapedspring mounted therein with its arms positioned at the side edges of theclosure, studs carried by the free ends of said arms and extendingoutwardly in opposite directions through the edges of said closure inposition to enter the sockets of said bills, the cross bar ofV saidspring being provided with a plurality of laterally extending loops toincrease the resiliency of said arms, and means for com- Y pressing saidarms to release said studs.

5. A link comprising hook-shaped ends connected at one side of the linkby a reduced neck having shoulders at its opposite ends, the other endsof said hooks being spaced apart a distance corresponding to the lengthof said neck, said free ends of the hooks having longitudinally alinedsockets therein, a closure comprising a cylindrical member revolublymounted on said neck with a hollow casing radiating therefrom and of alength spanning the space between said neck and'the free ends of saidhooks, said closure being of a width corresponding to the distancebetween the free ends of the and extending laterally outward through myhand in presence of two subscribing witsaicli( casing eoge inlllooslitiondto ener thle nesses. soc ets in sai ree oo en s, an pusbuttons mounted in the edge walls of said MARCO G' ZONGARO 5 casing andengaging the arms of said Witnesses:
